The Sewage (Inland Waters) Bill places a duty on water companies to ensure that untreated sewage is not discharged into rivers and other inland waters. The Bill will require water companies to set out plans progressively to reduce their reliance on combined sewer overflows (CSOs). It proposes increasing levels of transparency, as firms will be mandated to report publicly not just on the frequency and extent of sewage discharges from CSOs and any other sewer catchment assets, but also on the impact on water quality as this is enabled by advances in technology.
The Bill also proposes measures to upgrade drainage infrastructure to separate household sewage from surface water drainage, helping reduce the risk of overspills. It includes measures to reduce harmful products such as non-biodegradable wet wipes, commercial fats and oils from being disposed down the drains. It also proposes measures to expand the number of inland bathing waters and establish targets to increase those classified as “good” or “excellent”.
